1. The problem statement, all variables and given/known data A spring is hung from the ceiling. A 0.450-kg block is then attached to the free end of the spring. When released from rest, the block drops 0.150 m before momentarily coming to rest. (a) What is the spring constant of the spring? (b) Find the angular frequency of the block’s vibrations. 2. Relevant equations Ei = Ef [tex]\omega[/tex] = sqrt (k/m) 3. The attempt at a solution I cant figure out how to find part A. I know that once I find that I take that value and plug it into equation 2 to solve for the angular frequency.
